Genuinly one of the best people on youtuber deserves a million subs, helped over 16 thousand students 👏

[hajra]

youre a great help sir please keep going

[yokiiii]

Thank you so much! This video helped me sooo muchhh!!!😭 now I understand this topic very well!!💗

Yo, so i just wanted to ask if that video you made about chapter seven was enough of an explanation for pseudocode to do the exam, other than that thanks for everything youve done so far.

[chopztick]

Thank you soo soo much for theses videos you just saved my computer sciencce grades :D

Sir thnx a lot sir for your vedios . Really helpful sir. I am going through all your vedios only from the 1st vedio . Plz let me know if it is enough to study your vedio only (cz reading the text book and vedio is really difficult and have no time cz my exam is this Friday and the main exam is on April. @sir James

This is the code i wrote for the exam marks, and I made it to be suitable for any marks range. Can you check this?
marks = [[76, 65, 67], [32, 90, 75], [66, 77, 31]]
max_phy = marks[0][0] # I want this program to be suitable for any marks range, so I did not give max = -1
max_chem = marks[0][1]
max_bio = marks[0][2]
max_average = 0 # gave here so that it's a global variable
for student in range(0, 3):
total = 0 # to calculate average at the end
for subject in range(0, 3):
if subject == 0: # for phy
if max_phy <= marks[student][subject]:
max_phy = marks[student][subject]
elif subject == 1: # for chem
if max_chem <= marks[student][subject]:
max_chem = marks[student][subject]
elif subject == 2: # for bio
if max_bio <= marks[student][subject]:
max_bio = marks[student][subject]
total += marks[student][subject]
average = total / 3
if student == 0:
max_average = average # Gave this incase average < 0 so that there is no error
if max_average <= average:
max_average = average
print(max_average)
print(max_phy)
print(max_chem)
print(max_bio)

A weak away for paper 2 of mine sire and totally I was indeed dependent on your lectures for both physics and computer sir please tell me some important tips for paper 2

[YOTY-sswn]

Can we have more programming problems?

[muhdhyqel]

Wohoooo look @ James go! Jokes aside, great content!

[randomstuff-mdxr]

could we open multiple files at the same time

[ashnaimtiaz]

From where to get the software u are doing programming on in python kindly guide???

[cipicql]

I don't understand how to do task 2 on arrays

[hudabourini]

Hello Mr. James ....
Is it necessary to learn python for IGCSE o level exam or only Pseodocode ???

[jamesganleongyi]

Hey everyone, thanks for watching, hope the video helps! :)

By the way, you can purchase the slides I use here for personal revision (students) or teaching (teachers) 😉

Thank you!
